Abstract
Even if a belt layer or a belt-reinforcing layer is constituted of a nonmetal material, a belt is reliably detected to form a base tire of desired shape and size. When a tread rubber (10a) positioned on the radially outer side of the belt layer (10b) of a spent tire (10) is ground off by a grinding means (20), the hardness of the tread rubber (10a) is measured by a hardness measuring means (30). At the instant when the hardness of the tread rubber (10a), which has been measured by the hardness measuring means (30), reaches a predetermined hardness, the grinding operation of the tread rubber by the grinding means (20) is ended.
Description
Technical field
The present invention relates to a kind of method of retreads and equipment of grinding old tire (used tire) made.Particularly, the present invention relates to easily and the tread rubber of grinding old tire reliably.
Background technology
Pay on the basic tire by the tyre surface sticker that just contacts and to make automobile tyre with ground.Be enough to the kilter that further uses because the base tire also is in usually when paste paying tread rubber on basic tire and finished its life of product; therefore the tread rubber part owing to the use experience wear can recap again with new rubber or retreads material, thereby this tire can be used as retreads and reuses.The manufacture method of retreads generally is divided into two kinds: reshape method (hot retreading), the tyre surface sticker of decorative patternization is not paid on basic tire and these semi-finished product are set in the mould that is used for vulcanizing with decorative patternization; And precuring method (cold renovation), do not use mould and will vulcanize with the tyre surface sticker of decorative patternization and pay on the basic tire, with semi-finished product further sulfuration in the sulfuration drum.In in these two kinds of renovate methods any, all must at first in polishing, use the old tire that polishing machine will be to be renovated to be shaped to pre-determined configurations and size, to obtain basic tire.
Traditionally, obtain basic tire by the following method: at first, arrive belt up to this hole by using drilling machine etc. in the tread rubber of old tire, to get out at least one hole; By using the degree of depth in each hole of manual measurement such as rule; Determine the stock removal of old tire, the amount of grinding soon based on measured value; By using the grinding parts semi-automatic or automatically grind away the tread rubber of stock removal, remove, to form basic tire.Yet, under the situation that forms basic tire in the above described manner since when determining the stock removal of old tire the thickness of the tread rubber of manual measurement old tire, therefore following problem appearring: handles consuming time and unreliable when the negligible amounts of measurement point.
In order to address the above problem, for example, Japanese kokai publication sho 58-001546 communique and TOHKEMY 2002-86586 communique all disclose following equipment for grinding (grinding apparatus): this equipment for grinding is measured the thickness of the tread rubber of old tire by use metal detection sensor or current vortex sensor under the situation of not destroying tire, can automatically control the stock removal of the tread rubber of old tire, thereby be optimum value the thickness setting of the tread rubber on the basic tire.Equipment for grinding in the Japanese kokai publication sho 58-001546 communique is measured the thickness of the tread rubber in the old tire by the belt that uses metal sensor to detect old tire under the state that the old tire that is kept rotationally by maintaining body rotates; Remove the outer peripheral face of old tire by the grinding of grinding parts based on the thickness of the tread rubber that measures; And when reaching optimum value, the thickness of tread rubber stops the grinding of grinding parts.The equipment of TOHKEMY 2002-86586 communique adopts current vortex sensor to substitute above-mentioned metal sensor; The electromagnetic induction effect of the high frequency coil by using the current vortex sensor of arranging near the outer peripheral face of old tire is come the distance between measuring transducer and the belt; Calculate the thickness of the tread rubber in the old tire, remove the outer peripheral face of old tire based on the thickness of the tread rubber that measures by the grinding of grinding parts; And when reaching optimum value, the thickness of tread rubber stops the grinding of grinding parts.
Summary of the invention
The problem that invention will solve
Yet, measure the thickness of the tread rubber of old tire because use metal detection sensor or current vortex sensor, so the belt cord that constitutes belt be by situation about forming as nonmetallic materials such as polyester, glass fibres under, the disclosed equipment for grinding thickness of energy measurement tread rubber not in Japanese kokai publication sho 58-001546 communique and the TOHKEMY 2002-86586 communique.In addition, owing to reason the same reason as above, thereby the radial diameter of tire increases under the situation that is suitable for running at high speed when the radial outside that is embedded in the belt that is made of all-steel cord by the band bundle enhancement Layer that forms as banded organic fibers such as nylon along circumferentially reeling is run at high speed to be suppressed at tire, these equipment for grinding can not detect the existence of band bundle enhancement Layer, thus may be with band bundle enhancement Layer and tread rubber grinding together when the grinding tread rubber.
Therefore, the objective of the invention is to address the above problem, the basic tire that the objective of the invention is under following situation, to detect the belt of old tire reliably and form intended shape and size: the situation that forms belt by nonmetallic materials, the band bundle enhancement Layer that is formed by nonmetallic materials is embedded in the situation of the radial outside of belt, and the cord made by metal material of belt situation about constituting.

As shown in Figure 1, door shape bracing frame 2 is configured to stand on the ground.Cylinder 3 is installed on the bracing frame 2, makes cylinder 3 flatly extend towards the vertical portion of the opposite side that is positioned at bracing frame 2 2b from the central portion of the short transverse (above-below direction of Fig. 1) of the vertical portion 2a of the side that is arranged in bracing frame 2.The axial rearward end of the piston rod 3a of cylinder 3 is inserted in the bearing 5, and bearing 5 is fixed in a side of the support wheel rim (support rim) 4 of a side that is positioned at tire, thus, by bearing 5 and cylinder 3 by bracing frame 2 supported wheel rim 4 rotationally.
On the other hand, bearing 6 is fixed in the central portion of the short transverse (above-below direction among Fig. 1) of the side of vertical portion 2b.Turning cylinder 7 is inserted in the bearing 6, makes turning cylinder 7 to rotate around the axis identical with the axis of cylinder 3.Be positioned at the support wheel rim 8 and support wheel rim 4 pairings of the opposite side of tire, support wheel rim 8 is fixed to an axial end of turning cylinder 7.As a result, by bearing 6 and turning cylinder 7 by bracing frame 2 supported wheel rim 8 rotationally.
Operation by cylinder 3 give prominence to/is return piston rod 3a, the result has only support wheel rim 4 moving axially along cylinder 3, and support wheel rim 8 is maintained fixed at same position, thus, the support wheel rim 4,8 of pairing as described below along the central axis of tire 10 close to each other/separated from one another.Make support wheel rim 4,8 close to each other/modes separated from one another be not limited to only make as in the present embodiment in the support wheel rim 4,8 one (promptly, support wheel rim 4) to move, support wheel rim 4,8 can move together.Just, at least one side in the support wheel rim 4,8 along the central axis of tire close to each other/separated from one another.
When support wheel rim 4,8 was observed, drive motors 11 was arranged on the ground of reverse side of vertical portion 2b.14 framves of rotating band are between pulley 12 and pulley 13, and wherein, pulley 12 is fixed on the output shaft 11a of drive motors 11, and pulley 13 is fixed on the turning cylinder 7.Therefore, remove in the operation in the grinding of the tread rubber 10a of tire 10, when the operation by drive motors 11 was rotated output shaft 11a, support wheel rim 4,8 and the tire that is fixed on the support wheel rim 4,8 rotated integratedly around the central axis of tire 10.
As shown in Figure 2, the grinding parts 20 that are used for the tread rubber 10a of grinding tire 10 are set at the place ahead (right-hand side of Fig. 2) of bracing frame 2.Grinding parts 20 comprise and are arranged in ground base portion 21 and are installed in the pair of guide rails 22 of extending along fore-and-aft direction (right-hand man's side direction of Fig. 2) on the base portion 21.Movable plate 23 is supported on the guide rail 22 slidably.In addition, be installed on the movable plate 23 in the upwardly extending pair of guide rails 24 in side with the axially parallel of turning cylinder 7.Balladeur train 26 with polishing rotor (scraping) 25 is supported on the guide rail 24 slidably, and this polishing rotor 25 is used for the tread rubber 10a of grinding tire 10.By driving as driving mechanism (not shown) such as screw mechanisms, movable plate 23 and balladeur train 26 respectively along tire 10 radially and/or width move, thereby, balladeur train 26 can move by the outer peripheral face along tire 10 in horizontal plane, thereby polishing rotor 25 can move by the outer peripheral face along tire 10 in horizontal plane.
Therefore, by moving polishing rotor 25 as follows, tread rubber 10a is partly or entirely ground away or is removed from tire 10 and tire 10 is shaped to basic tire: the tire 10 that supports by support wheel rim 4,8 by the state that rotates from the driving force of drive motors 11 under, the polishing rotor 25 that is rotating moves along the outer peripheral face of tire 10 in horizontal plane.Base portion 21, guide rail 22, guide rail 24, movable plate 23, balladeur train 26 and polishing rotor 25 whole formation grinding parts 20.Yet the grinding parts can have the structure different with said structure.
In addition, as depicted in figs. 1 and 2, hardometer 30 as the hardness measurement parts is set at horizontal part 2c via for example position adjusting mechanism 31, horizontal part 2c is crossed between a pair of vertical portion 2a, the 2b of bracing frame 2, and position adjustments member 31 is used to regulate the position of hardometer 30 with respect to the tread rubber 10a of tire 10.For example, as shown in FIG., position adjusting mechanism 31 can be by constituting as lower member: vertical arm member 31a, its vertically (above-below direction among Fig. 2) connect horizontal part 2c; Vertical sliding motor 31b, it is fixed on the horizontal part 2c, be used for so that vertically arm member 31a can be vertically slidably mode keep vertical arm member 31a; Horizontal slip motor 31d, it is fixed on the end of vertical arm member 31a, be used for so that transverse arm member 31c can keep transverse arm member 31c along the axially movable mode of turning cylinder 7, axial (width of tire 10) of this transverse arm member 31c and turning cylinder 7 locatees abreast.Therefore, via vertical arm member 31a and transverse arm member 31c, by the driving force from vertical sliding motor 31b and/or horizontal slip motor 31d make hardometer 30 along tire 10 radially and/or width move.
When the hardness of the tread rubber 10a of the tire 10 that is measured by hardometer 30 reached predetermined hardness, control circuit was finished the grinding of 20 couples of tread rubber 10a of grinding parts.In the present embodiment, for example, the hardness of the belt 10b of tire 10 can be input to control circuit in advance, thereby can suitably control the operation of grinding parts 20 based on this information.In the present embodiment, " predetermined hardness " can be set to the value between the hardness before the grinding of the hardness of belt 10b and tread rubber 10a.
Based on the hardness of the tread rubber 10a that is measured by hardometer 30, control circuit calculates the stock removal of tread rubber 10a.In the present embodiment, the size controllably set for the hardness of the tread rubber 10a that is measured by hardometer 30 of the stock removal of tread rubber 10a is inversely proportional to.Particularly, when the hardness ratio of the tread rubber 10a that is measured by hardometer 30 during near the hardness before the grinding of the described tread rubber 10a of the hardness before the grinding of above-mentioned predetermined hardness and tread rubber 10a in the two, the stock removal of tread rubber 10a is configured to bigger than predetermined standard value.On the contrary, when the hardness ratio of the tread rubber 10a that is measured by hardometer 30 during near the above-mentioned predetermined hardness of the hardness before the grinding of above-mentioned predetermined hardness and tread rubber 10a in the two, the stock removal of tread rubber 10a is configured to littler than predetermined standard value.Based on the stock removal of determining like this, control circuit is suitably controlled the operation of grinding parts 20.Particularly, the driving mechanism (not shown) of grinding parts 20 make movable plate 23 and balladeur train 26 along tire 10 radially and/or width moves and the corresponding distance of stock removal determined like this, thereby the tread rubber 10a of tire 10 is ground stock removal.In addition, control circuit control equipment for grinding 1 makes the grinding of tread rubber 10a and the hardness measurement of tread rubber 10a carry out in alternately repeated mode.
Then, will the operation of the equipment for grinding 1 of above-mentioned old tire be described.At first, tire 10 is installed to support wheel rim 4,8, and for example the interior side direction tread rubber 10a from tread rubber 10a exerts pressure by be inflated to predetermined air pressure to tire.Then, tire 10 is rotated and is fixed to the position of expectation.Arm member 31a, the 31c of position adjusting mechanism 31 be according to sliding from the instruction of control circuit then, with the hardness measurement position at the outer peripheral face place of the tread rubber 10a that determines tire 10.The pressing 30a of hardometer 30 presses the outer peripheral face of hardness measurement position with certain load.As a result, pressing 30a is according to the hardness of tread rubber 10a and displacement.Hardometer 30 is based on the addendum modification of pressing 30a and measure the hardness of tread rubber 10a, and measurement result is outputed to control circuit.Control circuit is determined the stock removal of the tread rubber 10a of tire 10 based on this measurement result.
Then, by drive motors 11 support wheel rim 4,8 and tire 10 are rotated integratedly.Simultaneously, control circuit makes the movable plate 23 waited at position of readiness separately and balladeur train 26 move towards tire 10 along guide rail 22,24 based on the stock removal of determining like this, make polishing rotor 25 with high speed rotating, polishing rotor 25 is contacted with the tread rubber 10a of tire 10, and polishing rotor 25 is moved with the outer peripheral face of balladeur train 26 along tire 10, and the tread rubber 10a's of grinding removal tire 10 is part or all of thus.Then, measure the hardness of the tread rubber 10a of tire 10 once more by hardometer 30.Hardness at tread rubber 10a has reached under the situation that is input to the predetermined hardness in the control circuit in advance, finishes grinding.Hardness at tread rubber 10a does not also reach under the situation of predetermined hardness, is determined the stock removal of the tread rubber 10a of tire 10 once more based on the hardness measurement result of tread rubber 10a by control circuit.After this, as grinding before, based on the tread rubber 10a of the stock removal grinding tire of determining like this 10.With alternately and the mode that repeats carry out hardness measurement operation and the grinding action of tread rubber 10a, reach predetermined hardness up to the hardness of tread rubber 10a.When the hardness of tread rubber 10a had reached predetermined hardness, the hardness of tread rubber was in its optimum value.
In the present embodiment, following table 1 has specifically illustrated when by the grinding parts step by step during the tread rubber of grinding old tire, the result and the remaining tread rubber gage of the hardness of the tread rubber that is measured by hardometer in each stage.
Table 1
In the equipment for grinding 1 of the old tire of present embodiment, detect belt 10b by the hardness of measuring by hardometer 30 the tread rubber 10a of the old tire 10 of grinding.By reaching pre-determined hardness number and the basic tire that forms tread rubber 10a of the predetermined hardness value in the scope between the hardness number before the grinding of tread rubber 10a at belt 10b up to the hardness of the tread rubber 10a of old tire 10 with expectation thickness by the tread rubber 10a of grinding parts 20 grinding old tires 10.As " predetermined hardness " of the hardness that will finish grinding can be to each tyre type, be that each tire construction (according to the quantity of the quantity of belt, casing ply material, tread rubber material, band bundle enhancement Layer, tire specification etc.) is set in advance and stored.
Therefore, equipment for grinding 1 according to the old tire 10 of present embodiment, owing to utilize the hardness of belt to detect belt 10b in the mode different with traditional technology of passing through use metal detection sensor or current vortex sensor detection belt 10b, therefore, for example under the situation that belt 10b is made of the cord of making as nonmetallic materials such as organic fibers and the band bundle enhancement Layer that is constituting by cord as nonmetallic materials such as organic fibers be embedded under the situation of radial outside of belt 10b, can detect the belt 10b of old tire 10 reliably.
In addition, according to the equipment for grinding 1 of the old tire 10 of present embodiment, the size that the stock removal of tread rubber 10a is controlled so as to the hardness of the tread rubber 10a that is measured by the hardness measurement parts is inversely proportional to.Thus, grinding accuracy require not too strict, apart from the outermost surface of belt 10b position far away, stock removal is set greatlyyer, and is requiring position high-precision grinding, nearer apart from the outermost surface of belt 10b, and stock removal is set lessly.Therefore, can in the short grinding time, carry out high-precision grinding to tread rubber 10a.
In addition, the equipment for grinding 1 according to the old tire 10 of present embodiment carries out the grinding of tread rubber 10a and the hardness measurement of tread rubber 10a in alternately repeated mode, thereby can detect belt 10b accurately.
